An inverted V-type powertrain suspension device and an assembly method for its rear suspension

Abstract

The invention relates to an inverted-V-shaped power assembly suspension device and an assembling method for a rear suspension thereof. The inverted-V-shaped power assembly suspension device comprises a front suspension and a rear suspension, one end of the front suspension is fixedly connected with an engine case and the other end of the front suspension is fixedly connected with a frame side sill; the middle part of the rear suspension is fixedly connected with the middle part of a gearbox shell side plate, the two ends of the rear suspension are fixedly connected with the frame side sill, the rear suspension comprises block suspension rubber washer assemblies, rear suspension brackets and an arch-shaped cross sill, the two ends of the arch-shaped cross sill are respectively and fixedly connected with the tops of the two block suspension rubber washer assemblies, the bottoms of the block suspension rubber washer assemblies are fixedly connected with the frame side sill on the same side through the rear suspension brackets, the tops of the block suspension rubber washer assemblies are fixedly connected with the middle part of the gearbox shell side plate through transitional connecting supports, and the tops of the transitional connecting supports are fixedly connected with the bottom of the arch-shaped cross sill. The inverted-V-shaped power assembly suspension device and the assembling method for the rear suspension thereof have the advantages that not only can the vehicle longitudinal span between the front suspension and the rear suspension be increased, but also the vibration isolation performance is good, the service life is long and the assembling space is not greatly occupied.

Description

technical field [0001] The invention relates to an automobile powertrain mount, in particular to an inverted V-shaped powertrain mount and an assembly method for the rear mount, and is particularly suitable for increasing the span between the front and rear mounts of the powertrain , Improve the car buffer performance. Background technique [0002] As an important support and vibration isolation element of the powertrain, the engine mount has high requirements for the support and vibration isolation of the engine mount. The existing technology is a four-point mounting method. The engine rear mounting assembly is generally fixed on the engine flywheel housing or the clutch housing. The front and rear mountings have a small longitudinal span of the vehicle and cannot meet the rigidity in a specific direction. and strength requirements, poor vibration isolation performance, and due to more rigid contact, the impact deformation and dynamic deformation of the cushion assembly ar...
